DETAILED DESCRIPTION

In the following description, specific details are set forth although it should be appreciated by one of ordinary skill in the art that the systems and methods can be practiced without at least some of the details. In some instances, known features or processes are not described in detail so as to not obscure the present invention.

Embodiments of the present concepts include a system and method for improving productivity by store employees, associates, contractors, or the like, by providing instantaneous tactile feedback via a wearable navigation device to the wearer, which can direct the wearer to a destination of interest, example, a shelf, bin, and/or other storage location for stocking a store item.

FIG. 1 is a diagram illustrating an environment 100 for navigating an individual to a destination location for stocking an item at a store, in accordance with some embodiments. For example, an individual 11, or user, is in possession of one or more items 16 and wishes to bring the item 16 to a destination location 116 to stock the item 16 or otherwise move the item 16 to a desired location. Although item stocking is referred to in FIG. 1, other applications may equally apply where a user wishes to be directed to a destination location, not necessarily to stock an item.

The environment 100 includes a store 10, a network 30, a feedback converter 110, and a location finder 112. The store 10 may include a reference location 106 and the destination location, one or both of which may include a shelf, bin, freezer, and/or other structural element where store items may be stocked. In some embodiments, the feedback converter 110, location finder 112, store servers, and/or some or all of the network 30 may be physically present at the store 10. The store 10 may also include one or more servers (not shown) that perform well-known functions, for example, point of sale processing, inventory management, and so on. It is to be understood that the feedback converter 110, location finder 112, store server (not shown), and/or other computer systems of the environment 100 can take many forms and implementations, including hardware, software, or both. In embodiments where hardware implementations are present, the hardware processors can be part of one or more special purpose computers that execute computer program instructions which implement one or more functions and operations of the elements of the environment 100. Server 102 in the embodiment shown in FIG. 1 is a retail store server, but this is not meant to be limiting. Alternatively, features of the feedback converter 110, location finder 112, and/or store servers may be available via the internet, cloud computing services, or other remote server services.

A user 11 at the store 10 is in possession of a mobile electronic device 14 and a wearable navigation device 20. The mobile electronic device 14 and the navigation device 20 are each capable of exchanging wireless data with other hardware components of the environment, for example, the location finder 112, when the mobile computing device is located at a particular location. The mobile electronic device 14 can be a smartphone, handheld computer such as a tablet, or related device having a processor, memory, and display, and constructed and arranged for mobility, in particular, permitting the user 11, for example, an employee, to move about a store with the mobile electronic device 14.

Stored in the memory of the mobile electronic device 14 can include an application that processes data for pedometer locationing and for communicating with the wearable navigation device 20.

In other embodiments, the mobile electronic device 14 is not present, and the wearable device 20 is used to scan the item 16 and be directed to the destination location without involvement of the mobile device 14.

The navigation device 20 may be constructed and arranged for positioning about a wrist, waist, or other part of the body. The wearable navigation device 20 provides tactile feedback to the user 11, which may include sight, sound, vibration, or other haptic feedback for navigating the user 11 with the item 16 to a desired destination, for example, to a location of interest 116 for stocking the item 16. The location of interest 116 may have a length, width, and height. For example, the location of interest 116 may be a shelf that is six feet above ground level, and includes several shelves at different heights. Here, the wearable navigation device 20 provides tactile feedback that directs the user to the particular shelf six feet above ground level and distinguishes this shelf from the other shelves. For example, the information can be derived from available database information on modular-category-sequence (salesfloor) or aisle-section-height (backroom), or can be determined from scan data, for example, described herein.

As shown in FIGS. 2A-2C, the wearable navigation device 20 may include a band portion 102, barcode scanner 103, and a plurality of feedback devices 104, or nodes. The band portion 102 can be constructed and arranged for positioning about a body part, such as a wrist or waist. In other embodiments, the band portion 102 is flat, not ring-shaped, for attaching to a body portion such as the user's back or stomach region. In doing so, the feedback devices 104 on one side of the band portion 102 directly or nearly abuts the skin so that the skin can receive impulses or other sensory-related feedback, for example, heat, pressure, vibration, and so on, from a plurality feedback devices 104 at the band portion 102. The feedback devices 104 provide the pulses or other feedback in the form of sight, sound, and/or touch in a predetermined manner that indicates to the wearer 11 the direction of the destination location of interest 116, for example, generating pulses at a number of nodes 104 in a sequential pattern, or wave, or frequency. The nodes 104 can be positioned on multiple devices 20, for example, a device at each hip, each constructed and arranged to provide feedback according to embodiments herein.

The barcode scanner 103 is used for scanning a barcode or other location-identifying element 107 at a reference location 106 as well as the item 16 to determine the current location and orientation of the user 11, which in turn permits direction information to be generated and provided in the form of tactile feedback at the navigation device 20. Accordingly, the barcode scanner 103 may also be used to identify a desired location 116.

In some embodiments, the mobile electronic device 14 performs the scanning function instead of the wearable navigation device 20. Here, the wearable navigation device 20 communicates with the mobile device 14 to direct the user 11 to the destination location 116.

The wearable navigation device 20 may include at least one wireless transceiver 105 for communication with other electronic devices, for example, the feedback converter 110 and/or the mobile electronic device 14. The wireless transceiver 105 may exchange communication signals with the other electronic devices according to a communication protocol or type, such as, but not limited to, radio frequency (RF), WiFi, Bluetooth, and so on. In some embodiments, the navigation device 20 can communicate with the store server (not shown) for centralized location and direction processing for a dedicated or single-purpose location device.

When determining where to place the item 16 at its destination location 116, the user 11 may select at the mobile electronic device 14 the destination location 116. In particular, a display at the user interface of the electronic device 14 can display a button, window, via the software application, whereby the user 11 can enter the destination location 116 or selecting it from a dropdown menu. The selected location data can be output to the location finder 112 for processing.

The user 11 may scan the item 16 at or near the location 106 using the barcode scanner 103 to establish a current location. The item 16 that is scanned is the item that the user 11 needs to be directed to its location of interest. In doing so, the scan result can be output to the location finder 112. The location finder 112 determines that the barcode scan is generated by barcode scanner 103, and knows that the item 16 is at location 106. In other words, the known location 106 of the item 16 can be used to determine the direction for navigation for the user 11, which in turn can permit a path to be established from the current location to the intended location 116. Timestamps or related data can also be collected and processed by the location finder 112 to determine the location.

The user 11 may position the mobile electronic device 14 in a direction of, i.e., facing, the shelf 106 to determine a direction orientation. The wearable navigation device 20 may include an accelerometer or compass in some embodiments. In some embodiments, the user 11 scans a location-identifying element 107 such as an item, tag, shelf label, or the like at the shelf 106 to establish the location of the user 11 at the shelf 106 to establish a reference point, and to establish a reference heading or vector. In an embodiment where a compass is not used to determine heading, the heading will be assumed to be facing the shelf. The heading is needed to give directions accurately. The scan result can be output to the location finder 112. The location finder 112 can calculate a direction orientation of the user 11 based on the scan information provided from the scanner 103 and the location-identifying element 107 of the shelf 106 and provide the result to the wearable navigation device 20, for example, a location device or processor at the navigation device 20, which communicates with the tactile feedback emitters 104 to generate tactile feedback in response in a manner that permits the user to determine a general direction of the destination. For example, the tactile feedback can be generated as a wave-pattern by the feedback converter 110 based on the location information from the location finder 12. In some embodiments, the feedback was interpreted directly at the navigation device 20. For example, a signal corresponding to a “left turn” may be sent to the device 20 from the mobile device 14. In another example, a signal can be generated at a rate or frequency that increases as the user approaches the destination, for example, increasing pulses felt by the user's skin. In other embodiments, each node is controlled independently, for example, where the feedback converter 110 is located at a separate server.

Other embodiments may include, instead of a scanner on the mobile device 14 itself or the navigation device 20, a separate wired or wirelessly connected scanning unit may be used, for example, a ring-scanner or hip-mounted scanner, or other scanner at a different location than the mobile device 14 or navigation device 20.

As shown in FIG. 3, the wearable navigation device can be constructed as a wristband 20A, or as shown in FIG. 4, as a belt 20B. In some embodiments, the navigation device can be two or more devices located at different parts of the body, and each constructed and arranged to provide feedback via nodes 104. In some embodiments, the tactile feedback is generated as vibrations. For example, as described herein, nodes 104 are arranged so that the vibrations are provided in a sequential, or wave pattern, indicating three dimensional locations, e.g., left, right, forward, backward, up, down, or a combination thereof. In other embodiments, as shown in FIGS. 3 and 4, the wearable navigation device 20A, 20B (generally, 20) may include a plurality of feedback zones, for example, multiple vibration zones, pressure zones/nodes, or other tactile feedback, for example, gentle thermoelectric heating or cooling, for example, the device 20 is warmer in the direction that the wearer needs to go, and turns cooler away from where the user needs to go.

FIG. 5 is a diagram illustrating another environment 200 for navigating an individual to a destination location for stocking an item 16 at a store, in accordance with some embodiments. For example, a user 11 such as a store associate desires to bring an item 16 to a destination shelf 116.

The environment 200 includes a store 10, a network 30, a converter 110, and a location finder 112, which may be similar or the same of those described in FIG. 1. Details thereof will therefore not be repeated due to brevity.

Instead of a scanner located on the wearable navigation device 20, the environment 200 includes a plurality of stationary scanning devices 218 at a reference location 106, which can determine an orientation of the user 11. Each scanning device 218 serves as a predetermined location node, which is mapped to or otherwise associated with a particular store location such as an aisle, shelf, and so on. Therefore, unlike the environment of FIG. 1, there is no need to establish a relative location using a scanner on the wearable navigation device 20. Instead, the relative locations, and directions to those locations, are already established by the fixed location of the scanners 218. A mobile electronic device is not required to communicate with the scanning device 218. However, the scanning device 218 may communicate directly with the wearable navigation device 20, or indirectly via a server or the like. The user 11 may scan the item 16 using a scanner 218 at a location node to establish a current location of the user 11. The location node can be assigned to an aisle-section or other predetermined or “fixed” location, so that the location is established, and that the current location of the user 11 and item 16 are known. Since the location is fixed, the orientation of the user 11 is known. Also, the navigation device 20 at the scanning hub 218 can be identified by scanning a barcode on the navigation device 20, via wireless communication, and/or other identification techniques. In some cases, only one navigation device 20 is present at the store. Here, the navigation device 20 does not require a specific identifier for determining navigation information. After scanning the item 16, the navigation device 20 may include a sync button or the like that outputs a signal to the server 112 when selected, which instructs the server 112 to output navigation to the navigation device 20, as distinguished from other navigation devices which may be present at the store 10.

The location data, item and navigation device identifiers can be output to the location finder 112, or related server, whereby an association, or link, can established between the fixed scanner 218 and the wearable navigation device 20. In some embodiments, the linking device 208 links the user 11, or more specifically, the wearable navigation device 20 in possession by the user 11, to the selected location node automatically based on the nearest WiFi, Bluetooth, or other connection. Here, Wi-Fi triangulation, GPS, or other related techniques may be used to locate which wearable device 20 is nearby (for example, when many users are involved with moving items).

The location finder 112 can calculate from the data provided by the fixed scanner 218 direction signals, i.e., navigation information, that guide the user 11 from the fixed scanner 218 to the destination location 116. The location finder 112 can send the direction data to the wearable device 20, which in response can provide tactile feedback for navigating the user 11 to the destination 116. Navigation may occur by the location finder 112 having a set of instructions, which along with a compass or accelerometer at the wearable device 20, and tracking the movements, for example, turns, made by the user 11 during movement to the destination location 116. In other embodiments, the wearable device 20 can include a position sensor, for example, GPS, WiFi, and so on, which can provide data to the location finder 112 which in turn continuously tracks the user's movements and provides direction information.

The wearable navigation device 20 can generate tactile feedback in a similar manner as described in the environment 100 of FIGS. 1-4.

FIG. 6 is a diagram illustrating another environment 300 for navigating an individual 11 to a destination location for stocking an item at a store, in accordance with some embodiments. Here, a user may wish to remove an item from a bin 306A, for example, in a pick, where the individual 11, or user wearing a navigation device 302. Bin locations 306A, B (generally, 306) may be stacked vertically, horizontally, or both, for example, configured as an array. Although a bin is referred to in the example of FIG. 6, other locations may equally apply, for example, store shelves.

The user 11 may select at the mobile electronic device 14 a bin location where the user would like to put item 16. In other embodiments, the user 11 can select the item 16 which may have an intended location associated with it. A display at the user interface of the electronic device 14 can graphically present a button, window, via a software application stored in memory and executed by a processor. Here the user 11 can select a bin location, bin 306A. In some embodiments, a sales floor may have multiple locations for the same item 16. Bins, shelves, or a combination thereof may therefore be selected. The bin location is displayed may include an identity of an aisle, section, height/notch, or other location. The selection information can be output to the location finder 112. The item and bin location are associated with each other, or linked, by a unique identifier stored at the location finder 112, or a database in communication with the location finder 112.

User 11 establishes a reference direction by facing a reference bin 306B, and establishes a current location by scanning bin label 307 (either with barcode scanner 103 or scanner on phone 14) which establishes user's current location and orientation.

The location finder 112 can determine direction data based on the received information for directing the user to the intended bin location 306A and sends result to a location device 302 on wristband.

Tactile feedback can be provided from the navigation device 302. For example, the tactile feedback can be generated by the feedback converter 110 in response to location information from the location finder 112. Since a location may be established, in three dimensions, for example including along a vertical axis, tactile feedback can be provided that informs the user 11 of the vertical location, for example, by vibrations at zones 1 and 2 shown in FIG. 3 corresponding to an up direction and a down direction, respectively. In other embodiments, referring to FIGS. 2A and 2C, wave patterns or other tactile feedback can be generated that indicate an up direction or a down direction. The tactile feedback may therefore direct the user 11 to the bin 306A location for removing item 16 from bin 306A.

FIG. 7 is a diagram illustrating another environment 400 for navigating an individual to a destination location, in accordance with some embodiments.

The user 11 may select at the mobile electronic device 14 a bin location where the user would like to put item 16. Although bin locations are referred to in FIG. 7, other locations may equally apply, for example, shelves. The user 11 may select at the mobile electronic device 14 a location where the user would like to put item 16, for example, a bin, shelf, or both. In other embodiments, the user 11 can select the item 16 which may be assigned to multiple locations, for example, assigned to one or more bins 406A1-406A6. In other embodiments, a sales floor may have multiple locations for the same item. Here, a selection of locations may include one or more bins, shelves, and/or the like. A display at the user interface of the electronic device 14 can graphically present a button, window, via a software application stored in memory and executed by a processor. Here the user 11 can select a bin location, bin 406A1. The selection information can be output to the location finder 112. The item and bin location are associated with each other, or linked, by a unique identifier stored at the location finder 112, or a database in communication with the location finder 112.

User 11 establishes a reference direction by facing a reference bin 306B, and establishes a current location by scanning bin label 307 (either with barcode scanner 103 or scanner on phone 14) which establishes user's current location and orientation.

Location finder 112 determines a closest or most easily accessible bin based on a technique that processes aisle/rack/height information and determines a direction to that location and sends result to the navigation device 402 via the converter 110. The tactile feedback emitters 104 at the navigation device 402 may provide tactile feedback, for example, according to feedback zones described above, to direct the wearer 11 to a region of intersection at a length, width, and height of the location of the bin 406A1.

Tactile feedback can be provided from the navigation device 402 in a similar manner as the navigation device 302 of FIG. 6. For example, the tactile feedback can be generated by the feedback converter 110 in response to location information from the location finder 112.
